Simple and elegant , white never fails!
Add foliage. A living plant is a great way to add color and dimension to a bath. A ficus or palm would make a nice statement if you have an available corner. Smaller plants can help break up the monotony of a long counter. Orchids and bamboo grow well indoors and love humidity. A traditional pot creates a more formal feel, but if you want a casual vibe consider teacups, bowls or apothecary jars.
